So except the comfort/etc issues with running a smaller tyre, I would be more efficient running a 20mm or 23mm on the Kuota, to increase the gap from 2-3mm to closer to 10mm? Currently it's 25mm with the negligible gap, running with the prescribed 'closer-is-better' (that you've disproved).
Ah, Kuota Kaliber. My guess is that the leading edge of the seat tube fucks the airflow so comprehensively that anything happening behind it is moot :-)
Amazing, thanks.
